American boat Puma took a slim lead Sunday as the Volvo Ocean Race fleet headed for Miami on the 4,800-nautical mile sixth leg of the nine-stage event.

U.S. skipper Ken Read of Newport, R.I., who won the previous leg earlier this month, was just ahead of overall leader Telefonica of Spain, which slipped from first to last in an in-port race Saturday after sailing around the wrong marker buoy.

In the overall standings, Telefonica has 149 points and leads Groupama with 133, Camper (124) and fourth-place Puma (117). Abu Dhabi with 56 points and Team Sanya (25) complete the six-boat fleet.

The 39,000-nautical mile race is scheduled to finish in the first week of July in Galway, Ireland.
